JUNCTION CITY — The annual Truck Function in Junction event came to an abrupt end Saturday night when a tow truck snagged overhead power lines across Highway 99W, cutting power to more than 150 customers of Pacific Power and Light.

The tow truck was crossing the highway during the fifth annual Truck Function when a malfunctioning remote control for the boom caused it to raise without the operator knowing at the inter­section of 16th Street and Highway 99W, according to a news release Sunday from the Junction City Police Department.

No one was hurt, and no one was to blame, officials said. The tow truck driver cooperated and was not cited.

The Truck Function in Junction is an annual Junction City festival that showcases all manner of big rigs and other commercial trucks and tricked-out pickup trucks.

The one-day event was scheduled to end at 9 p.m., but it stopped Saturday about 8:30 p.m. when the tow truck’s heavy-duty boom, flying an American flag, snapped telephone poles in half, ripped equipment from the roofs and walls of nearby buildings and blew multiple utility circuit breakers, police said.

Power was restored by 12:40 a.m. Sunday to all but 39 of the 151 households affected by the outage.
